Bently Nevada 3500/25-01-01-02 Enhanced Keyphasor Module
Bently Nevada 3500/25-01-01-02 Enhanced Keyphasor Module for 3500 Machinery Protection System. Half-height, two-channel module converts proximity probe or magnetic pickup signals into digital Keyphasor outputs. ATEX/IECEx/CSA certified for Class 1 Zone 2 hazardous areas. Provides precise timing for shaft speed, phase, and vector measurements.
Key Features
2-channel half-height module. Input range 1 to 1,200,000 cpm (0.017 to 20 kHz). Output range 1 to 99,999 cpm. Auto or manual threshold triggering. Buffered Keyphasor outputs at front and rear. -24 Vdc transducer power supply. 3.2W typical power consumption. ATEX/IECEx/CSA Class 1 Zone 2 approval. Supports up to four Keyphasor signals standard, eight in paired configuration. Direct replacement for 125792-01.

Ordering Code Breakdown
3500/25-01-01-02
A:01 – Single half-height 2-channel Keyphasor card.
B:01 – I/O module with Internal Terminations.
C:02 – ATEX/IECEx/CSA (Class 1 Zone 2) approval.
Installation Notes
Install in half-height front slot using mounting adapter. I/O module occupies corresponding full-height rear slot. For hazardous area installation, follow control drawing 149243 or 149244. Configure trigger threshold (auto or manual) and hysteresis per application. Use Internal Terminations (B:01) for standard proximity probe applications.
Engineering Advantages
ATEX/IECEx/CSA Class 1 Zone 2 certification enables installation in hazardous areas. Supports up to eight Keyphasor signals in paired configuration. Expanded frequency range handles multi-event-per-turn inputs up to 20 kHz. Direct replacement for legacy 125792-01 modules. Buffered outputs at front and rear simplify external diagnostics. Field-upgradeable firmware protects investment.
